Australia, Brisbane: Quinbrook Infrastructure Partners has successfully connected the stage one substation of its Brendale-based Supernode battery energy storage system to Queensland’s high-voltage transmission network.
Located 23 km north of Brisbane, back-feed energisation was achieved via a dedicated link to Powerlink Queensland’s South Pine substation – a major transmission hub through which about 80 % of the state’s electricity flows daily. The substation sits adjacent to Quinbrook’s Supernode Data Centre and battery site.
The first stage of the project, rated at 260 MW, is progressing in line with delivery plans agreed with Origin Energy, Quinbrook’s offtake partner for stages one and two. “We are pleased to continue working closely with Powerlink to advance all future stages of the Supernode project,” said Quinbrook CEO and Regional Leader Brian Restall.
When fully built, the first three phases will deliver 780 MW / 3,074 MWh of storage capacity, supported by long-term offtake agreements with Origin Energy and Stanwell Corporation. The project’s fourth phase, now in advanced development, will include Quinbrook’s first eight-hour battery storage solution, designed in partnership with Chinese manufacturer Contemporary Amperex Technology Co. Limited.
Quinbrook Senior Director James Allen described the Supernode as “a game-changer for Queensland’s renewable integration and grid stability,” adding that it demonstrates the next generation of firming and storage capability for Australia’s energy transition.
The project is expected to achieve initial commercial operation in 2025, with full operation targeted for 2026.
